Verizon tests optical sensing with NEC

Verizon conducted a proof-of-concept test to assess whether fiber optic cables laid in the ground can serve as distributed optical sensors to collect information on city traffic patterns, road conditions, road capacity, and vehicle classification information.

The trial used new optical sensor technology developed by NEC with software underpinned by artificial intelligence (AI) for intelligent traffic monitoring including the measurement of vehicle density, direction, speed, acceleration, deceleration, and more. The trial used fiber already deployed in the ground.

The fiber sensing system coexisted with existing Wavelength Division Multiplexing (WDM) communication channels on the same fiber with minimal impact to data communication capacity. The distributed multi-parameter sensor system evaluated various properties of back-scattering light, which can be used to derive the static strain, dynamic strain, acoustics, vibrations and temperatures for each fiber segment. This allows users to identify detected signatures and to translate those back-scattering signals into actionable information over a wide range of area previously unattainable by conventional sensors. With this unique technology provided by NEC, Verizon is able to use existing telecom networks, which were not built for sensing purposes, to generate valuable new data and to automatically analyze various environments.

“This test marks an important milestone for technology that could provide a huge leap forward for those building smart cities and those tasked to manage them,” said Adam Koeppe, Senior Vice President of Technology Planning and Development with Verizon. “Instead of ripping up tarmac to place road and traffic-sensing technology, cities will be able to simply piggyback Verizon’s existing fiber optic network.”

Results from this trial were reported jointly at OFC 2019 by Verizon and NEC (download PDF at https://www.osapublishing.org/abstract.cfm?uri=OFC-2019-Th4C.7).

“NEC has a strong history of leadership in the area of optical fiber technology. The results obtained from this joint research program with Verizon are a great advancement for smart city business opportunities, especially for safer city solutions such as the conservation of roads and the utilization of traffic information. We are confident that these cutting-edge solutions will provide meaningful new value for optical fiber networks,” said Atsuo Kawamura, Executive Vice President of NEC.

NEC demos adaptive network control for radio resources

NEC demonstrated adaptive network control technology in its multi-access edge computing (MEC) servers and base stations in a use case concerning automated driving. These trials successfully allocated radio resources (frequency bandwidth and time slots) to vehicles with high urgency as part of providing services that require real-time communication control for mobile networks.

NEC said the tests confirmed that base stations can support safe driving by steadily suppressing communications delay time to within 100 milliseconds by preferentially assigning radio resources to vehicles with high urgency based on the analysis results of vehicle location information, camera images of the area around the road and other data.

In the experiment, an automated driving environment was simulated in an anechoic chamber. The MEC server detected pedestrians by analyzing images of street cameras at an intersection, collected information on the location of surrounding vehicles, and shared such information with individual vehicles in real time. The commercial LTE base station was placed near the intersection, and multiple devices, such as vehicle models, cameras and smartphones, were connected to create a situation where there was a shortage of wireless resources.

NEC adds 5G Traffic Management

NEC launched an enhanced Traffic Management Solution (TMS) for 5G that improves the throughput of high-speed networks that support data transfer rates of more than 5 Gbps. 

NEC said 5G requires greater throughput from core networks through the wireless access networks. However, there will be a mixture of networks with different communication speeds, such as 4G and 5G, and, therefore, it is necessary to assure network stability at the time of a terminal's handover between different types of networks.

NEC's enhanced TMS features advanced component software that increases the performance and accuracy of analytics. Moreover, Dynamic TCP Optimization, a function that enables control in response to changing network conditions, has extended its scope to the ultrahigh-speed range of 5Gbps or more.

The company claims its enhanced TMS in a 5G test environment has improved 5G communications quality by increasing throughput by approximately 24% in the ultrahigh-speed range of 5Gbps or more; reducing download time during the handover from 4G to 5G by approximately 27%; and reducing the time to reach the maximum speed during the handover from 4G to 5G by approximately 64%.

"NEC contributes to a better experience for end users and more efficient network operations for CSPs by continuing to enhance TMS," said Kazuhiro Tagawa, General Manager, Network Solutions Division, NEC Corporation. "Our TMS has been adopted by over 20 CSPs worldwide and we look forward to seeing it drive the further advancement of 5G."

NEC and Google test subsea modulation using probabilistic shaping

NEC and Google have tested probabilistic shaping techniques to adjust the modulation of optical transmission across the 11,000-km FASTER subsea cable linking the U.S. and Japan.

The companies have demonstrated that the FASTER open subsea cable can be upgraded to a spectral efficiency of 6 bits per second per hertz (b/s/Hz) in an 11,000km segment -- representing a capacity of more than 26 Tbps in the C-band, which is over 2.5X the capacity originally planned for the cable, for no additional wet plant capital expenditure. The achievement represents a spectral efficiency-distance product record of 66,102 b/s/Hz.

The field trial was performed with live traffic on neighboring channels.

The companies said their test used near-Shannon probabilistic-shaping at a modulation of 64QAM, and for the first time on a live cable, artificial intelligence (AI) was used to analyze data for the purpose of nonlinearity compensation (NLC). NEC developed an NLC algorithm based on data-driven deep neural networks (DNN) to accurately and efficiently estimate the signal nonlinearity.

"Other approaches to NLC have attempted to solve the nonlinear Schrodinger equation, which requires the use of very complex algorithms," said NEC's Mr. Toru Kawauchi, General Manager, Submarine Network Division. "This approach sets aside those deterministic models of nonlinear propagation, in favor of a low-complexity black-box model of the fiber, generated by machine learning algorithms. The results demonstrate both an improvement in transmission performance and a reduction in implementation complexity. Furthermore, since the black-box model is built up from live transmission data, it does not require advance knowledge of the cable parameters. This allows the model to be used on any cable without prior modeling or characterization, which shows the potential application of AI technology to open subsea cable systems, on which terminal equipment from multiple vendors may be readily installed."

Transpacific FASTER Cable Enters Service with 60 Tbps Capacity

The world's highest capacity undersea cable system has entered commercial service -- six fiber pairs capable of delivering 60 Terabits per second (Tbps) of bandwidth across the Pacific.

FASTER is a 9,000km trans-Pacific cable connecting Oregon and two landing sites in Japan (Chiba and Mie prefectures). The system has extended connections to major hubs on the West Coast of the U.S. covering Los Angeles, the San Francisco Bay Area, Portland and Seattle. The design features extremely low-loss fiber, without a dispersion compensation section, and the latest digital signal processing technology.

Google will have sole access to a dedicated fiber pair. This enables Google to carry 10 Tbps of traffic (100 wavelengths at 100 Gbps). In addition to greater capacity, the FASTER Cable System brings much needed diversity to East Asia, writes Alan Chin-Lun Cheung, Google Submarine Networking Infrastructure.

Construction of the system was announced in August 2014 by the FASTER consortium, consisting of China Mobile International, China Telecom Global, Global Transit, Google, KDDI and Singtel.
